Crypto team expects no packages other than gnutls to use nettle directly. Nettle comes with weaker API/ABI guarantees in RHEL; FIPS certifications treat nettle as part of gnutls FIPS module, but they do not cover nettle API.

The RHEL-9 predecessor to this request was https://bugzilla.redhat.com/show_bug.cgi?id=1954483

Hope this is just a matter of ./configure'ing it --without-nettle
